For me the meaning of life is to learn, educate, and teach each other. Death is a factor, but that doesn't mean a person should just give up, and accept the end. Life goes on, our meaning is to ensure that the chain of humanity continues. Love is also a great factor in life. We should not only love our family but also express that love to others. People depend on others for help. That's were we should come in, and help them. To be human doesn't mean eat, sleep, sex, build a family. It also means to help others.
I agree completley with WindDancer!!!
If our purpose was to merely eat, sleep, reproduce, and die, we would not have been given a consciousness. We have intelligence, and creativity.
I believe the purpose of life is to love. That's it, plain and simple.
